Crumb rubber is the toughest value in bumper plates. Made from recycled rubber and tested to withstand 30,000 drops, these plates land quieter and gentler than iron ever could, on both your floor and your barbell. Pairs run 10 to 45 lb, with 160 and 260 lb bundles for full setups.

Genuine PRx Performance
Synergy Custom Fitness is a PRx Performance retail partner. Every PRx free weight on our site is the same gear PRx sells directly, fulfilled and shipped to your door by PRx itself.
30,000 Drops, Tested
PRx durability tests these plates through thirty thousand drops. That is years of daily deadlifts, cleans, and bailed squats before the plates blink. Real proof, not marketing.
Recycled and Rugged
Crumb rubber construction turns recycled material into one of the toughest training surfaces available, at the friendliest price point in the bumper world. Tough on purpose, twice over.
Kind to Floors and Bars
Rubber absorbs the landing instead of transmitting it. Less noise, less bounce, and far less stress on garage concrete and barbell sleeves than metal plates.
Uniform 17.75 Inch Diameter
Every weight lands the bar at the same height, so deadlifts pull from regulation position whether the bar carries 10s or 45s. Every rep starts the same way.
Bundles That Outfit a Gym
The 160 lb bundle covers 45, 25, and 10 lb pairs. The 260 lb bundle adds 35 and 15 lb pairs, a complete graduated set in one order.
Stores With Everything Else
Synergy plate storage racks and wall mounted holders keep bumper pairs ordered by size, off the floor, and next to the platform, where they belong between sessions.
